TREATMENT OF WASTEWATER FROM A PERSONAL CARE PRODUCTS INDUSTRY BY FENTON PROCESS
Phase II - Viva Voice

INTRODUCTION
• Industrial wastewaters are one of the major sources
of pollution.
• In India, approximately 13500 MLD of
wastewaters is generated by industries. (CPCB
ENVIS 2014)
• Only 60% of W/W is treated.
• It is a major concern for environment.
PERSONAL CARE PRODUCT INDUSTRY
• Personal care product industries comes under FMCG
industry.
• There are 20 top personal care products manufacturers
in India.
• Hindustan Unilever Limited is the largest personal care
product industry in India.
• HUL has a share of about 54% in personal care product
category.
SEGMENTAL BREAK-UP OF PERSONAL CARE MARKET
PERSONAL CARE PRODUCTS SCENARIO IN INDIA
• Total market 23 million tons in volume.
• 7 million tons market for bathing soaps.
• 16 million tones market detergents soaps & bars.
• 30% detergent cakes.
• 70% detergent powder.
WASTEWATER GENERATION BY PCP’S INDUSTRY
• Personal care product industries contributes
around 8% to the total industrial wastewater
generation in India.
• Total wastewater generated by PCP’s industries in
India is around 1080 MLD. ( CPCB ENVIS 2014)
NEED FOR THE STUDY
• Presently the wastewater from a personal care
products industry is being treated by conventional
aerobic biological method.
• The process involves coagulation, sedimentation ,
aeration(ASP) and secondary settling tank.
• This process takes more time and energy to treat
the wastewater.
• Hence in order to economize the time and energy,
an attempt is planned to treat by Fenton process.
OBJECTIVES OF THE STUDY
• To study the characteristics of the wastewater
from personal care products industry.
• To study the existing treatment process and
effluent characteristics from the treatment plant.
• An attempt to modify the present process with
Fenton process.
• Comparison of the treatment efficiency and costs.

• Raw wastewater contains LAS of 11 mg/l and ABS of 12 mg/l.
•Optimum conditions are pH = 3, FeSO4 = 90 mg/l , H2O2 = 60 mg/l, treatment time is 50 mins.
•Obtained 95% removal of ABS & LABS by Fenton process.

•Effluent contains 400 mg/l of phosphorous & 35 g/l of COD.
•Optimum conditions are pH= 3, H2O2 = 63gm/l , FeSO4 = 11 gm/l . •Phosphorous reduced to 0.93 gm/l and COD reduced to 0.28 gm/l.
